as president bashar al-assad syrian troops launched another attack on the rebels in the northern part of his country. there is a heavy turkish military presence this. clearly, the artillery has been given the grown light to fired. it is a dangerous dynamic and we could have a regional war. turkey is part of nato, so turkey could invoke the collective defense clause of that treaty and it would draw on the united states and other western allies to recollect and defend turkey if it gets into a war with syria. the other dynamic, the syrian rebels need help. it could be a point that syrian rebels launch shells at turkey to try and start a war that obviously they would get a lost help from going up against the common enemy, president bashar al-assad. >>trace: and the syrian rebel, how are they doing? >>guest: they have not been doing great but this week they did get some good news in an unusual victory. they took over a syrian air defense space which means they got the missiles inside that base, and if they can figure out how to use the missiles against president bashar al-assad's air force
